1. What other programming languages integrate with JSON?
This question is simple but may gauge how comfortable you are working in other platforms or languages. While you may not do this in your role, you may be tasked with building integrations or adopting a broader scope of understanding for a variety of platforms and languages.

You can curate a response that answers the question without overcomplicating the topic. You may consider speaking in layman's terms for conciseness and understanding.
Example: "Newtonsoft is a .net framework that allows JSON to operationally function. It's considered a serializer that allows you to edit JSON commands directly in an internal framework. The syntax you use with Newtonsoft, otherwise known as JSON.net, is very simplistic and easy to understand for programmers of all skill levels."

Example: "While there are many advantages to using JSON, every platform and language has its own unique set of advantages and disadvantages. JSON isn't the best to use for large-scale data products or for projects that require commenting or readability. With more than a few simple data sets, the output can become complex and difficult to understand, leading to an increased margin for error."
